This, combined with high fertility rates, will accelerate Muslim population growth.
In all major regions where there is a sizable Muslim population, Muslim fertility exceeds non-Muslim fertility.
The growth of the Muslim population also is helped by the fact that Muslims have the youngest median age (23 in 2010) of all major religious groups, seven years younger than the median age of non-Muslims (30).
A larger share of Muslims will soon be at the point in their lives when people begin having children.
The expected growth of Islam around the world is perhaps the most striking finding in the recent Pew Research Center report projecting the future of religious groups.
Indeed, Muslims will grow more than twice as fast as the overall world population between 20 and, in the second half of this century, will likely surpass Christians as the world’s largest religious group.
While the world’s population is projected to grow 35% in the coming decades, the number of Muslims is expected to increase by 73% – from 1.6 billion in 2010 to 2.8 billion in 2050.In 2010, Muslims made up 23.2% of the global population.Four decades later, they are expected to make up about three-in-ten of the world’s people (29.7%).By 2050, Muslims will be nearly as numerous as Christians, who are projected to remain the world’s largest religious group at 31.4% of the global population.The main reasons for Islam’s growth ultimately involve simple demographics.To begin with, Muslims have more children than members of the seven other major religious groups analyzed in the study.
